A construction defect complaint usually contains many different causes of action and theories of recovery. There are different product liability causes of action that apply to devleopers of homes in subdivisions that do not apply to a contractor who remodels or builds one home. In both you can plead causes of action for express warranty based on written warranties and a cause of action for implied warranty which is not in writing but goes under the general principal that construction will be fit for its intended purpose and if it is defective, it is warranted for repair or recovery of the cost of repair under the implied warranty theory.

In general you may have both contract and tort claims and remedies, and you may have 2 types of claims, but I wouldn't be so quick to see parallels between tenancy claims and construction claims. They're not at all the same thing and they're rarely implicated in the same fact pattern.
Your situation is complex and not really suited to an Avvo Q&A, and given that your written agreenments presumably have attorney's fees clauses, you need to consult a lawyer to discuss your legal as well as available administrative remedies through the CSLB and the DFEH, respectively.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
